[0039] It should be noted that, as Figure 11 As shown, the strip of Chinese herbal medicine is made up of several small bags of Chinese herbal medicine 6 connected together. The cutting mechanism is used to cut the long strip of Chinese herbal medicine into small bags of Chinese herbal medicine 6.
[0040] like Figure 1-6 As shown, this cutting mechanism includes a frame 1, a conveying assembly 2, and a cutting assembly 3. The conveying assembly 2 includes an upper transmission belt 21 and a lower transmission belt 22 mounted on the frame 1 and arranged opposite to each other. The upper transmission belt 21 and the lower transmission belt 22 rotate in opposite directions so that the Chinese herbal medicine slices are clamped between the upper transmission belt 21 and the lower transmission belt 22 and move forward. The cutting assembly 3 is located at one end of the conveying assembly 2. The cutting assembly 3 includes a cutting board 31, a guide frame 32, a fixing seat 33, and a blade 34. The cutting board 31 is mounted on the frame 1, the guide frame 32 is mounted on the cutting board 31, the fixing seat 33 is slidably connected to the guide frame 32, and the blade 34 is fixedly connected to the bottom of the fixing seat 33.
[0041] In this embodiment, both the upper drive belt 21 and the lower drive belt 22 are belt conveyors. The upper drive belt 21 and the lower drive belt 22 are arranged opposite to each other, and their rotation directions are opposite. It can be understood that the upper drive belt 21 is located above the lower drive belt 22, that is, the lower side belt of the upper drive belt and the upper side belt of the lower drive belt 22 move in the same direction. Under the clamping and driving of the lower side belt of the upper drive belt and the upper side belt of the lower drive belt 22, the Chinese herbal medicine slices belt moves along the movement direction of the lower side belt of the upper drive belt and the upper side belt of the lower drive belt 22, and finally moves to the cutting blade assembly 3; since the cutting blade 31 is installed on the machine... Specifically, the cutting table 31 is located at the end of the lower belt of the upper transmission belt and the upper belt of the lower transmission belt 22, receiving the conveyed Chinese herbal medicine slices. A guide frame 32 is mounted on the cutting table 31, a fixed seat 33 is slidably connected to the guide frame 32, and a blade 34 is fixedly connected to the bottom of the fixed seat 33. When the slices move to the cutting table 31, the guide frame 32 moves towards the cutting table 31, driving the blade 34 to move towards the cutting table 31. The blade 34 cuts the Chinese herbal medicine slices, thus cutting and tearing the slices into small bags of Chinese herbal medicine slices 6. This greatly improves the cutting efficiency of the Chinese herbal medicine slices, thereby improving the dispensing efficiency of the bags of Chinese herbal medicine slices 6. As one embodiment, such as... Figure 7As shown, the bottom of the blade is provided with several cutting edges 341, which facilitate the cutting of Chinese herbal medicine slices.
[0042] like Figure 5 and 6 As shown, the guide frame 32 includes two guide rods 321 and a top rod 322 vertically disposed at both ends of the cutting board 31. The top rod 322 is fixedly connected to the end of the two guide rods 321 away from the cutting board 31. The fixing base 33 is provided with two guide holes 331, and the two guide rods 321 are respectively inserted into the two guide holes 331, so that the fixing base 33 is slidably connected to the guide rods 321.
[0043] In this embodiment, the top rod 322 is fixedly connected to the end of the two guide rods 321 away from the cutting table 31. The guide rods 321 are vertically arranged at both ends of the cutting table 31. The top rod 322 and the two guide rods 321 form a gate shape, which ensures the structural strength of the guide frame 32. The fixed seat 33 is provided with two guide holes 331. The two guide rods 321 are respectively inserted into the two guide holes 331, that is, the fixed seat 33 can move up and down along the two guide rods 321, thereby driving the blade 34 to move up and down. The blade 34 cooperates with the cutting table 31 to cut the Chinese herbal medicine slices into small packages of Chinese herbal medicine slice bags 6.
[0044] like Figure 5 and 6 As shown, the cutter assembly 3 also includes two sets of buffer members 35. Both sets of buffer members 35 are fixedly connected to the bottom of the fixed base 33, and a receiving space is formed between the two buffer members 35. The blade 34 is located in the receiving space.
[0045] In this embodiment, two sets of buffer members 35 are fixedly connected to the bottom of the fixed base 33, and a receiving space is formed between the two buffer members 35. The blade 34 is located in the receiving space. When the cutting assembly 3 cuts the Chinese herbal medicine strip, the fixed base 33 moves toward the cutting table 31. The buffer member 35 first contacts the Chinese herbal medicine bag 6. Under the action of the buffer member 35, the blade 34 reduces its moving speed and then cuts the Chinese herbal medicine strip, so as to avoid the blade 34 from being too fast and being damaged when it comes into contact with the cutting table 31.
[0046] like Figure 5 and 6 As shown, specifically, the buffer 35 includes an elastic post 351, a clamping plate 352, and an elastic strip 353. One end of the elastic post 351 is fixedly connected to the bottom of the fixing base 33, and the other end of the elastic post 351 is fixedly connected to the clamping plate 352. The elastic strip 353 is fixedly connected to the side of the clamping plate 352 away from the elastic post 351.
[0047] In this embodiment, one end of the elastic column 351 is fixedly connected to the bottom of the fixing base 33, and the other end of the elastic column 351 is fixedly connected to the clamping plate 352. When the buffer member 35 contacts the cutting board 31, the elastic column 351 applies an elastic force to the clamping plate 352, which plays a buffering role and realizes the buffering effect of the buffer member 35. In addition, the elastic rubber strip 353 is fixedly connected to the side of the clamping plate 352 away from the elastic column 351. The elastic rubber strip 353 contacts the Chinese herbal medicine strip first, which plays a protective role for the Chinese herbal medicine strip. Before the blade 34 cuts the Chinese herbal medicine strip, the Chinese herbal medicine strip has been pressed and clamped by the buffer member 35, which can better fix the Chinese herbal medicine strip and facilitate the cutting of the Chinese herbal medicine strip. As one embodiment, the elastic column 351 is a spring or an elastic rubber column.
[0048] like Figure 8 As shown, the cutting board 31 is provided with a cutting groove 311 that is adapted to the blade 34, and the cutting groove 311 is arranged along the length direction of the cutting board 31.
[0049] In this embodiment, the cutting table 31 is provided with a cutting groove 311 adapted to the blade 34. When cutting the Chinese herbal medicine strip, the blade 34 continues to move toward the cutting groove 311 after contacting the Chinese herbal medicine strip, thereby cutting the Chinese herbal medicine strip to form a small bag of Chinese herbal medicine 6. The cutting groove 311 is arranged along the length of the cutting table 31, and the length of the cutting groove 311 can fully accommodate the blade 34, ensuring that the blade 34 can smoothly cut the Chinese herbal medicine strip and avoiding collision between the blade 34 and the cutting table 31, which would damage the blade 34.
[0050] like Figure 8 As shown, the cutting board 31 has an inclined portion 312 on the side away from the transport component 2. The inclined portion 312 is arranged along the length direction of the cutting board 31, and the inclined portion 312 is inclined from the top of the cutting board 31 toward the bottom of the cutting board 31.
[0051] In this embodiment, an inclined portion 312 is provided on the side of the cutting table 31 away from the conveying component 2. The inclined portion 312 is arranged along the length of the cutting table 31. After the Chinese herbal medicine slices are cut into small bags of Chinese herbal medicine slices 6 by the blade 34, the Chinese herbal medicine slice bags 6 slide down the inclined portion 312 to the conveying mechanism of the next process under their own gravity because the inclined portion 312 is inclined from the top of the cutting table 31 to the bottom of the cutting table 31. This effectively avoids the Chinese herbal medicine slice bags 6 from forming a blockage at the cutting table 31 and improves the smoothness of the continuous operation of the cutting mechanism.
[0052] like Figure 1-6As shown, the cutting mechanism further includes a drive assembly 4, which is mounted on the frame 1. The drive assembly 4 is used to drive the fixed seat 33 to reciprocate up and down along the guide frame 32. The drive assembly 4 includes a drive motor 41, a mounting base 42, a rotating shaft 43, and a connecting rod 44. The drive motor 41 is mounted on the frame 1, and a drive wheel 45 is provided at the output end of the drive motor 41. The mounting base 42 is mounted on the frame 1 and located at the bottom of the cutting table 31. The rotating shaft 43 is rotatably connected to the mounting base 42. Cams 46 are fixedly connected to both ends of the rotating shaft 43. A driven wheel 47 is provided on the rotating shaft 43. The drive wheel 45 and the driven wheel 47 are connected by a belt (not shown in the figure). One end of the connecting rod 44 is rotatably connected to the outer edge of the cam 46 through a spherical bearing 48, and the other end of the connecting rod 44 is rotatably connected to the end of the fixed seat 33 through a spherical bearing 48.
[0053] In this embodiment, the drive assembly 4 drives the fixed base 33 to reciprocate up and down along the guide frame 32, thereby driving the blade 34 to reciprocate up and down along the guide frame 32, thus automatically cutting the Chinese herbal medicine slices. Specifically, the rotating shaft 43 is rotatably connected to the mounting base 42, and the driving wheel 45 and the driven wheel 47 are connected by belt drive to drive the motor 41 to rotate, thereby driving the rotation. Cams 46 are fixedly connected to both ends of the rotating shaft 43. The cams 46 rotate with the rotating shaft 43. Since one end of the connecting rod 44 is rotatably connected to the outer edge of the cam 46 through the spherical bearing 48, and the other end of the connecting rod 44 is rotatably connected to the end of the fixed base 33 through the spherical bearing 48, the rotation of the cam 46 drives the connecting rod 44 to move along the outer edge of the cam 46, so that the connecting rod 44 drives the fixed base 33 to move up and down along the guide frame 32, thereby realizing the continuous cutting of the Chinese herbal medicine slices.
[0054] like Figure 9 and 10 As shown, the cutting mechanism also includes a machine cover, which is mounted on the machine frame. The machine cover is provided with a feed inlet and a discharge outlet. The feed inlet is located at the end of the conveying component away from the cutting component, and the discharge outlet is located at the end of the cutting component away from the conveying component.
[0055] In this embodiment, the feed inlet is located at the end of the conveying component away from the cutting component, and the discharge outlet is located at the end of the cutting component away from the conveying component. The herbal medicine slices belt enters the machine cover from the feed inlet. Under the clamping and driving of the lower belt of the upper transmission belt and the upper belt of the lower transmission belt, the herbal medicine slices belt moves toward the cutting component and finally moves to the cutting component. The cutting component then cuts the herbal medicine slices belt to form small bags of herbal medicine slices.
[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
